Dr. Arinze Okoli’s research is at the interface of Microbiology, Systems Biology, Biochemistry, Virology, Biosafety Science and Natural Product research. The biomedical fields are interlinked in the research projects due to his aim to understand complex biological mechanisms through studies of microbial (including virus) physiology, genetics and ecology. His approach is whole organism/cell analyses using analytical techniques in Systems Biology, including Proteomics, Transcriptomics, Bioinformatics and Molecular Biology to understand host-microbe & microbe-environment interactions.

Dr. Okoli received his PhD in 2009 from the University of New South Wales, Sydney, Australia, where he investigated the molecular basis of Enterohepatic Helicobacter species’ adaptations to hosts and environment.

Ongoing projects include

Functional genomics of vaccine relevant and naturally occurring orthopoxviruses
Read more about the project here.

Physiological and molecular aspects of microbial response to glyphosate – (an industrial herbicide and environmental pollutant), and its breakdown product – AMPA (aminomethylphosphonic acid)
Read more about the project here.

Molecular basis for bacteria bio-flocculant production (funded by the South African & Norwegian Cooperation – SANCOOP)
Read more about the project here.

Risk Assessment

Dr. Okoli also provides scientific advices that assist the Norwegian Ministry of Environment in the safety evaluation of (1) genetically modified vaccines and medicinal products; and (2) genetically modified foods and feeds.

Follow this link to GenØks assessment page. Due to strict regulations only the assessments regarding genetically modified foods and feeds will be available for the public.
